目的 探究白内障超声乳化手术中通过物理方法对前后囊膜进行抛光以减少后发性白内障(PCO)的效果。方法 研究年龄相关白内障患者92例(104只眼),年龄60～75岁，晶体混浊分级为Ⅱ～Ⅳ级。在进行角膜缘陡轴2.4mm微切口超声乳化术时，使用眼用指环型抛光器行前囊膜周边360°抛光及冲洗式球形磨砂抛光器进行后囊膜抛光。观察术中及术后眼视力或最佳矫正视力、后囊膜变化情况。同时，选择同期96例(106只眼)角膜缘陡轴2.4mm微切口白内障乳化术患者作为对照组进行比较。结果 术后1、3、6个月及1年、2年时后囊浑浊的发生率分别为0.96%(1/104)、0.96%(1/104)、1.92%(2/104)、2.88%(3/104)和5.77%(6/104),与同期未进行囊膜抛光的病例相比，差异显著(P<0.05)。结论 白内障超声乳化手术中进行前后囊膜抛光的患者术后PCO的发生率显著低于未进行囊膜抛光的患者。

Objective To study the effect of polishing the anterior and posterior capsule membranes through physical methods in cataract phacoemulsification surgery to reduce the occurrence of posterior capsule occlusion(PCO).Methods A study was conducted on 92 age-related cataract patients(104 eyes) aged between 60～75 years, with a grading of lens opacity ranging from grade II to IV.When performing corneal edge steep axis 2.4 mm micro incision phacoemulsification, an ophthalmic ring shaped polisher was used to perform 360° polishing around the anterior capsule, and a flushing spherical frosted polisher was used to polish the posterior capsule.The intraoperative and postoperative visual acuity or best corrected visual acuity, as well as changes in posterior capsule were observated.Meanwhile, 96 patients(106 eyes) who underwent corneal steep axis 2.4 mm micro incision cataract phacoemulsification surgery during the same period were selected as the control group for comparison.Results The incidence of posterior capsule turbidity at 1 month, 3 months, 6 months, 1 year, and 2 years after surgery was 0.96%(1/104),0.96%(1/104),1.92%(2/104),2.88%(3/104),and 5.77%(6/104),respectively.The difference was significant compared with cases that did not undergo capsule polishing during the same period(P<0.05).Conclusion Patients who underwent anterior and posterior capsule polishing during cataract phacoemulsification surgery had a significantly lower incidence of postoperative complications compared to those who did not undergo capsule polishing.
